BECEPTACLE.

.Application led April 5, 1926.A Serial No. 99,928.

My invention relates broadly to receptacles and more particularly to receptacles Jfor radio vacuum tubes.

An object of my invention is to provide a receptacle having individual socketsfor the eception of the prongs of a vacuum tube ase.

Another object is to provide a receptacle in which the Contact members encircle and grip the prongs of the base of avacuum tube.

A further object is to provide a vacuum tube receptacle in which the tension of the terminals againstpthe prongs of .a vacuum tube will remain constant.

5 With the above and other objects in View the invention consists in the construction, combination, and arrangement of parts as will be hereinafter more fully described.

Reference is to be had to the accompanying drawings in which like reference characters indicate corresponding parts throughout the several views, and in which Figure 1 is a top View of a device embodying my invention, 4

Figure 2 is a section on the line 2--2 of Fig. 1,

Figure 3 is a bottom view,

Figure 4 is an enlarged fragmentary view showing the details of one of the sockets, and

Figure 5 is a view showing a terminal and contact spring.

Referrin more particularly to the drawings, 6 is a ody member composed of one of the phenol condensation products or other suitable insulating material in one piece and with a plurality of openings 7 therethrough, so positioned that they will receive the prongs P of a vacuum tube. The body is provided on its under side with a. plurality of recesses 8, each of which opens to the sides of the body through grooves 9. The body is also provided with a circular upstanding collar C on which the tube base B is seated when the tube is in its operative position. The terminals 10 are made of brass and are so constructed that one end is ring-shaped while the other is bent to receive conductorsecuring elements 11. The ring-shaped ends are placed in the recesses while the other ends extend to the exterior of the receptacle through the grooves.

A contact coil spring 12, preferably constructed of phosphor bronze wire, but it is to be understood that other suitable spring ma- .member by fastening means 14 and holds the terminals and the contact springs in place. Passageways 15 therein register with the openings 7 in the body member.

It will be understood that the above description and accompanying drawings compehend only the general and preferred emdyment of my invention and that various minor changes in details of construction,

proportion and arrangementof parts may be made wit-hin the scope of the appended claims without sacrificing any of the advantages of my invention.

What I claim as new is:

1. In a socket for a vacuum tube, a base of insulating material having a plurality of apertures therein and adapted to receive the prongs of a vacuum tube, a plurality of conducting members mounted within the base, one end of each conducting member extending outwardly from the base and terminating in a terminal connection, the other end of each member extending within the base and terminating below one of the apertures therein in a loop, a coiled spring mounted within the loop and adapted to grip the sides of the prongs of a vacuum tube when extended through the apertures in the base.

2. In a socket for a vacuum tube, a base of insulating material having a plurality of apertures therein and adapted to receive the prongs of a vacuum tube, a plurality of conducting members mounted within the base, one end of each conducting member extending outwardly from the base and terminating in a terminal connection, the other end of each member extending within the base and terminating below one of the apertures therein in a loop, a coiled spring mounted within the loop with the axis of the coil parallel to the face of the base and adapted to grip the sides of the prongs of a vacuum tube when extended through the apertures in the base.

3. In a socket for a vacuum tube, a base of insulating material having a plurality of apertures therein and adapted to receive the prongs of a vacuum tube, a plurality of conducting members mounted Within the base, one end of eaeh conducting member extending outwardly from the base and nerminai-ing ina terminal connection, the other end of each member extending Within the base and terminating below one of the apertures therein in e, loop, o @oiled spring mounted Within Les-meen? the loop with the axis o the coil parallel to the fase of lie base and each -turn of the coil in a, plane substantially radial with re- 10 speci: i'o the center of Jshe loop, the center of the loop coinciding with the center of the corresponding aperture in the base.
